SPECIFICATION forming part Of Letters Patent NO. 628,603, dated July 11,1899.

Application filed August 20, 1898. Serial No. 639,154. (No model.) i

To all whom, it may concern:

Beitknown thatwe,GEORGE A. MABRY and JOHN T. MORGAN, of Roswell, in thecounty of Cobb and State of Georgia, have invented certain new anduseful Improvements in Flows; and we do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which.

form part of this specification. r

This invention relates to subsoil attachments for plows, its objectbeing to provide such an attachment which may be attached to anyordinary turning-plow to work in advance of the plow-point in a furrowalready made and to so connect the attachment to the plow-beam that itmay be easily and quickly moved into or out of operative position.

With these objects in view the invention consists of the several detailsof construction, combination, and arrangement of parts, as will behereinafter fully described, and the novel features of which will bedefined in the claims.

In the drawings, Figure l is a side elevation.

of a plow provided with our improved attachment, the latter being ininoperative position. Fig. 2 is a similar view taken from theoppositeside and showing the attachment in operative position. Fig. 3 is a rearview of the subsoil attachment, the lever being partly broken away. Fig.4: is a horizontal section on the line m of Fig. 3.

Similar reference-numerals indicate similar parts in the severalfigures.

1 indicates an ordinary turning-plow, 2 the plow-beam, and 3 theplow-handles. t is'a notched curved bar, one end 5 of which is extendedin a straight line and bears against one side of the plow-beam. On theopposite side of the plow beam we employ a short straightbar 6, and thelatter, as well as the end portion 5 of the curved bar, is provided withaseries of holes 7 to receive the clamping-bolts 8, one above and theother below the plow-beam. By this arrangement the curved bar can beeasily and firmly secured to any ordinary-sized plow-beam.

The end portion 5 of the curved bar has a pin 9 projecting outwardlyfrom it, on which the lever 10 is pivoted. Any suitable means may beemployed to retain the lever on the pin, such as a nutll and washer 12,as indicated in the drawings. The lever is provided with the ordinaryspring-latch 13 to engage the notches in the quadrant, the pivot-pinbeing the center from which the curve in the bar is struck.

Referring now to Figs. 3 and 4, it will be seen that the lower endportion of the lever is bent into U shape and that one member 14 of anan gle-plate rests against the front edges of the arms of the U-shapedportion, while the other member 15 of the plate rests against the sideof one of said arms. The subsoiler proper is indicated by 16, andconsists of a curved plateof any desired length and width. Its lower endwill preferably be formed with an obliquely-disposed cutting edge, asindicated at 17, while its upper portion will rest against the memberlat of the angle -plate. One or more securing-bolts 18 will extendthrough the subsoiler, themember 14., and the space between the arms ofthe U-shaped portion of the lever, and a nut 19 will be secured on eachbolt to engage the rear edges of said arms, and thereby securely clampthe angle-plate and subsoiler to the lever. The

member 15 of the angle-plate extends rearwardly beyond the lever andwhen the subsoiler is in operative position will engage the landside ofthe plow and hold the subsoiler stationary on the points of the plow.

This attachment is designed to be used principally'on hillsides wherethe land is preferably all turned one way, the invention being to turn afurrow going one way and subsoil going back in the same furrow. Thedevice struction may be resorted to. Without departing from the spiritor sacrificing any of the advantages of our invention.

Having described the invention,we claim- 1. The combination with aturning-plow, of a subsoiler pivoted to the plow-beam and movable intooperative position in contact with the plow-point and in advance thereofand having a plate attached thereto to engage the landside of the plowsubstantially as specified.

2. The combination with a turning-plow, of a lever pivoted to theplow-beam, asubsoiler connected to the lower end of the lever to work inadvance'of the plow-point, and a plate secured to the lever to engagethe landside of the plow when the subsoiler is operating substantially.as specified.

3. The combination with a turning-plow, of a notched curved bar havingone of its ends extended in substantially a straight line, a pivot-pinprojecting from the straight extension and forming the center from whichthe curve of the bar is struck, a lever pivoted on said pin, a subsoilercarried by the lower end of the lever, aplate attached to the subsoilerto engage the landside of the p'low when the subsoiler is operating anda spring-latch on the lever to engage the notches in the barsubstantially as described.

4. The combination with a turning-plow, of a lever pivoted to theplow-beam and having its lower end portion bent into U form, an
